Hybrid Software Defined Networking

Software Defined Networking (SDN) promises to ease design, operation and management of communication networks. However, SDN comes with its own set of challenges, including incremental deployability, robustness, and scalability. Those challenges make a full SDN deployment difficult in the short-term and possibly inconvenient in the longer-term.
We explore effective hybrid SDN architectures that combine SDN with a more traditional networking approach based on distributed protocols. In a number of use cases, hybrid SDN architectures combine the strengths of traditional and SDN approaches, mitigating their respective limitations. As such, they provide incentives to (partially) transition to SDN, and can be appealing even as long-term design points.

Advantages and opportunities of hybrid SDN architectures are shown in an increasing number of research contributions. An overview of the most relevant works in the area, grouped by covered topic, is provided in the following.
